FCC filing indicates LG Nexus 5

The evidence that LG and Google are working together to produce the Nexus 5 mobile phone is starting to stack up.

Documents, which have emerged from the US Federal Communications Commission (FCC), appear to suggest a smartphone known by the codename of LG D820.

Although the numbers don't indicate whether it is the Nexus 5, it does say that the handset will be covering a lot of North America, which is standard for a flagship handset.

According to Engadget, the official documents indicate the device will have Bluetooth 4.0, NFC and looks to be compatible with every major American network except Verizon's LTE 750.

It's still unclear whether the Nexus 5 will be a project from LG and Google, but the evidence appears to be mounting up to suggest that they are, despite earlier denials.

Reports indicate that the search engine giant accidentally unveiled the device at the Android 4.4 launch event. According to GSMArena, Google showed a video of the event which included an employee using the device, though it has now been removed.
